| Doc Text: |
A flaw was found in pypdf, a pure-python PDF library. A remote attacker can exploit this vulnerability by crafting a malicious PDF file containing manipulated XMP metadata entity declarations, which are data embedded within a PDF file. When the affected system parses this metadata, it can lead to excessive memory consumption. This memory exhaustion can result in a Denial of Service (DoS) condition, making the application or system unresponsive.
